SUCTlON-PLATE FOR ClGAR-WRAPPER-CUTTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 687,677, dated November26, 1901.

Application filed August 3, 1901. Serial No. 70,305- (No model.)

To @ZZ whom, it may concern:

Beit known that I, NAPOLEON DU BRUL, a citizen of the United States, anda resident of Cincinnati, in the county of Hamilton and State of Ohio,have invented a certain new and useful Suction-Plate for Cigar-Wrapper-Cutting Machines, of which the following is a specification.

My invention relates to the construction of the suction-plate formingpart of a cigar-Wrapper-cuttin g platen or table. I have heretoforeconstructed these suction-plates with a series of openings groupedwithin an area corresponding substantially to the wrapper to be cut fromthe tobacco-leaf and leaving an uninterrupted cutting path surroundingthe group of perforations and also with a series of perforations outsideof the cuttinglpath and substantially conforming thereto, so that theportion of the leaf forming the Wrapper is held in place until rolledupon the cigarbunch and the portion of the leaf forming the Waste isprevented from ruffling up during the cutting operation and untilremoved by the operator, while the whole leaf is held more securelyWhile cutting.

The object of my present invention is to so construct these plates thatwhen the tobaccoleaf is laid thereon and subjected to the suction theleaf will be drawn down over a shoulder or into a groove or depressionall around the cutting-path in such a manner as to indicate to theoperator the portion of the leaf that will be taken out to form theWrapper, and thus enable him to judge beforehand how to place the leafto secure the most economical results or get the most wrappers out of agiven leaf,

My invention will be fully understood upon reference to the accompanyingdrawings, in Which-- Figures l and 2 are respectively a plan and atransverse section of a perforated suction-plate, illustratingoneembodiment of my invention, Fig. 2 being a section on the line AA ofFig. l; and Fig. 3 is an additional section on the line B B of Fig. 1.Fig. 4 is a transverse section corresponding to Fig. 2, showing a slightmodification in the form of the groove embodied in Fig. l. Figs. 5 and 6are respectively a plan and a vertical sec=i tion on line C C, Fig. 5illustrating another embodiment of the fundamental principle of myinvention. 1

Referring to Figs. l to 4, inclusive,` l represents a suction-plate of acutting platen or table formed with a group of air-suction perforations2, arranged within an area conforming to the cigar-wrapper to be cut andsurrounded by an uninterrupted cuttingpath 6o 3, on the outer side ofwhich and conforming thereto are a series of perforations 4. The objectof my present invention being to cause a depression or drawing downofthe tobacco-v leaf to result from the suction through the perforations4, I form the plate along thel line of these perforations or in closeprox'- imity thereto or in proximity to some eqluiva-f lent airsuctionpassage or passages through the plate with a depression or groove ordrop 76 in the level of the plate, so that when airsuction iscommunicated beneath the leaf the latter will be drawn down over theshoulder or edge formed by the grooved depression g or drop in the levelof the plate and will indicate clearly to the operator just what portionof the leaf will be removed by cutting out the wrapper when the leaf isin that position, so that the operator may judge at once Whether he isapplying the leaf in position to 86 enable him to cut therefrom thegreatest possible number of wrappers. This feature is obviously of greatimportance, because it insures the economy in material used Withoutmaterially retarding the operator. If the leaf is not in exactly theright position, he may shut off the air-suction' momentarily and shiftthe leaf slightly, so as to get it just Where it is desired.

According to Figs. 1,2, 3, and 4 my invenoo tion is carried out byforming a groove which connects the perforations 4, this groove beingrepresented at 5 in Figs. 2 and 3 as of semicircular form and at 5a inFig. 4 as of angular form. In either case the depression or drop isprovided, which leaves an edge or shoulder just outside of andconforming to the cuttingpath, and when the leaf is drawn down over theedge or shoulder the purposes of my invention are fully accomplished.

According to Figs. 5 and 6 the depression or drop is provided by havinga raised or elevatedlsuction-plate la, through which the perforations 2are extended, such plate 1a be-V IOO ing proportioned so as to providethe cuttingpath 3, but to terminate just Within the series of outerperforations 4, and thus provide the shoulder or edge, or, in otherWords, to leave the depression beyond the cutting-path,which willindicate the position of the wrapper in the leaf as soon as air-suctionis applied. 5b indicates this drop or depression formed by the raised orelevated plate in Figs. 5 and 6.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In combination With a suction-plate for cigar-Wrapper-cuttingmachines having an uninterrupted cutting-path overwhichaknife may travelto cut a Wrapper from a leaf laid l thereon; an air-suction meansoutside of said cutting-path, and a drop or depression in connectiontherewith conforming in outline to the cutting-path, and into which theleaf is drawn by the air-suction to indicate the outline of the Wrapperin the leaf.

2. A suction-plate for cigar-wrapper-cuteene?? ting machines having acutting-path to rel ceive a knife for cutting out the Wrapper and a dropor depression in the surface conforming to said cutting-path andindicating the outline of the Wrapper in the leaf.

3. In a cigar-wrapper-cutting machine, a cutting-platen having a pathconforming to the wrapper to be out, upon which a knife may travel tocut the Wrapper, means for communicating air-suction to the leaf outsideof said cutting-path and with a portion of the platen conforming inoutline to the cutting-path, raised above the adjacent portion of saidplaten whereby a drop or depression is provided to indicate the outlineof the Wrapperin the leaf.

The foregoing specification signed this 26th day of July, 1901.
